Wireless Numeric Keypad vs. AmazonBasics AAA Alkaline

One of the streaming media players behaved funny, which always results in a numeric keypad battery replacement. This AmazonBasics AAA alkaline was down to about 0.5 V and long past its best-used-by date:

Numeric keypad – 5 year Amazon AAA Alkaline

Nigh onto six years isn’t bad, particularly as it hasn’t leaked electrolyte all over the negative terminal.

Suggestions that Amazon monitors their Marketplace sellers to figure out what’s profitable, then promote a Good Enough house brand product to kill off the competition, seem to describe the situation just about perfectly.

Jonas Peeler Repair

The blade on one of the Jonas vegetable peelers cracked, which suggests it’s the counterfeit version:

Jonas Peeler – cracked blade

I grooved the metal pin running through the handle:

Jonas Peeler – shaft grooving

A brass tube from the Little Tray o’ Cutoffs and some epoxy should hold things together forevermore:

Jonas Peeler – epoxy

The rainbow colors come from an instantly aborted attempt to silver-solder the parts together. The fact that I even tried a stunt like that shows I’m definitely not the brightest bulb in the chandelier these days.

Lyme Disease

For reasons that made sense at the time, two weeks ago I ventured outside the house. A few days later, this appeared:

Lyme Disease – arm rash

The pallid skin over on the left comes from a bike glove. The central bump is one of those annoying sebaceous hyperplasias appearing after a Certain Age and not relevant here.

Having been around this particular block a few times, Mary recognized the diffuse red rash, sleeping 30 of 36 consecutive hours, and a day-long 103 °F fever as Lyme disease. I’m currently taking 100 mg of doxycycline twice a day and (after a week) feeling better, while sleeping a lot more than usual at random intervals during the day.

We’re both highly aware of Lyme disease: Mary routinely dresses in a complete overlayer of permethrin-sprayed clothing and I generally strip-and-shower immediately after any yard work in similarly sprayed, albeit less enclosing, attire. In this case, we think a tiny Deer Tick nymph affixed itself to the outboard side of my wrist, where I could neither see nor feel it, and (because I didn’t take a shower after being outside for only a few minutes) remained attached long enough to infect me.

Caught and treated early, Lyme disease generally does not progress into “post-treatment Lyme disease”, an ailment rife with what can charitably be described as serious woo, despite some evidence of actual disease.

Some of Mary’s Master Gardener cronies have endured co-infections of Babesia microti and we’ll be watching for those symptoms after doxycycline tamps down the obvious problem.

I’ll be puttering very carefully around heavy machinery and posting irregularly for a few weeks …

Memo to Self: the Basement Shop has a lot to recommend it!

Small Spider vs. Marmorated Stink Bug

Spiders know how to handle much larger prey:

Spider draining Marmorated Stinkbug

Apparently the stink bug’s armor doesn’t count for much when the spider has the luxury of attacking through a weak spot in the underbelly after the critter stops struggling.

Stink bugs cause considerable damage to crops (notably apples) in the Hudson Valley, but they haven’t been the existential catastrophe we all expected when they first arrived.

Hooray for spiders!

OXO Not-salt Grinder: Aluminum Shaft

Having recently emptied the OXO pepper grinder we (mistakenly?) bought as a salt mill, I took it apart for a deep rinsing and cleanup:

OXO salt-pepper mill – aluminum shaft

It turns out the somewhat corroded square shaft is aluminum, neither the cheap steel I expected nor the stainless steel it should be. Perhaps OXO cost-reduced the shaft, discovered aluminum is a poor choice in a saline environment, and changed the packaging to compensate?

Removing / installing the Jesus clip requires careful whacking with a hollow-tip punch against the shaft, with the whole affair laid flat on shop towels, the handle held down to prevent rotation, and the wrap-around body capturing the escaping clip.

Shaft corrosion as of Summer 2020:

OXO Salt Mill – corrosion

Soaking the body in hot water got rid of salt crusts and filled the shell with water. There being no way to completely dry the thing, I parked it in the sun for a day, refilled it, and was unsurprised when the (dried) salt turned into an assortment of moist crystals.

We obviously need a real salt mill …

Dirt Devil Vacuum Tool Adapters

Being the domain expert for adapters between a new vacuum cleaner and old tools, this made sense (even though it’s not our vacuum):

Dirt Devil Nozzle Bushing - solid model — Dirt Devil Nozzle Bushing – solid model

The notch snaps into a Dirt Devil Power Stick vacuum cleaner and the tapered end fits a variety of old tools for other vacuum cleaners:

Dirt Devil Nozzle Bushing top view - solid model — Dirt Devil Nozzle Bushing top view – solid model

Having some experience breaking thin-walled adapters, these have reinforcement from a PVC tube:

Dirt Devil adapter - parts — Dirt Devil adapter – parts

A smear of epoxy around the interior holds the tube in place:

Dirt Devil adapters - assembled — Dirt Devil adapters – assembled

Building the critical dimensions with a 3D printed part simplified the project, because I could (and did!) tweak the OpenSCAD code to match the tapers to the tools. Turning four of those tubes from a chunk of PVC conduit, however, makes a story for another day.

The OpenSCAD source code as a GitHub Gist:

	cylinder(r=(FixDia + HoleWindage)/2,h=Height,$fn=Sides);

	}

	PolyCyl(PipeOD,AdapterOAL + 2*Protrusion,NumSides);
	}

	}

The taper in the code almost certainly won’t fit whatever tool you have: measure thrice, print twice, and maybe fit once …

Another Snapper

An approaching cyclist warned to watch out for the snapping turtle:

Snapping Turtle – DCRT near Page Park – front – 2021-09-24

This one claims the pond near Page Industrial Park along the Dutchess Rail Trail:

Snapping Turtle – DCRT near Page Park – rear – 2021-09-24

We’ll not dispute any snapper’s territory!

I’m hauling PYO apples from Prospect Hill Orchards in the hills on the west side of the Hudson; it was a lovely fall day for a 25 mile ride!
